Republican voters in New Hampshire decided to throw the election away. They embraced three MAGA candidates in the Senate and two Houses races. Bolduc and Leavitt (the nominee for NH-01) are both far right Trumplings who have pushed the Big Lie. Burns in NH-02 attacked his primary opponent, the more moderate mayor of Keene, for being pro-choice. That's a pretty stupid line of attack in a libertarianesque state like New Hampshire.
All three of these candidates will likely lose and it's unfortunate because the Republicans had a real shot of flipping these races. Hassan, the Democratic Senate incumbent, has approval ratings in the toilet, but she'll get reelected to a second term now. Conservatives have spoken and decided to embrace Trumpiness and reelect a slate of Democrats to represent them in November.
